Speed is set by a digital signal, so no variable frequency drive is needed. The housing is rated IP55 in the manufacturer documents. It runs from -13 to 140°F with a rated MTBF of 40,000 hours. Sound is rated at 68 dB or less, measured three meters from the fan center. The fan measures about 23.39 × 22.05 × 12.2 in and weighs 23.15 lbs.\u003c\/p\u003e\u003ch2\u003eMounting and Controlling a 20 Inch High Velocity Fan\u003c\/h2\u003e\u003cp style=\"text-align: justify;\"\u003eAttach the included stand to the fan body with the supplied screws.
